Key Technical Advantages
1. High-Precision Gear Manufacturing
Advanced precision gear grinding ensures micron-level gear mesh clearance, delivering volumetric efficiency exceeding 95% with minimal internal leakage. Precision-ground gear profiles effectively reduce pressure ripple for stable system operation.
2. Lightweight High-Pressure Aluminum Body
High-strength aluminum alloy construction provides excellent pressure resistance while significantly reducing overall weight. The compact Group 1 design is ideal for space-constrained installations.
3. Superior High-Speed Performance
Supports continuous operation up to 6000 rpm—a leading specification in its class. High-speed capability delivers greater flow output in a smaller package, maximizing system power density.
4. Long-Life Bearings and Sealing System
High-performance bearings with optional Viton (FKM) seals provide excellent chemical resistance and thermal stability for demanding applications. Viton seals significantly extend service life in harsh operating environments.
5. 100% Drop-In Interchangeability
Manufactured to unified European standards, the X1P series is fully interchangeable with equivalent models from Parker, Bosch Rexroth, Marzocchi, and Casappa. No adapters or modifications required—direct replacement reduces downtime and maintenance costs.
Application Areas
Micro hydraulic power units
Agricultural machinery (tractor hydraulic systems, combine harvesters)
Material handling equipment (forklifts, stackers)
Construction equipment (mini excavators, skid steer loaders)
Industrial lubrication systems
Custom OEM hydraulic systems
Expert Maintenance Tips
Rotation Direction Verification: Confirm pump rotation matches system requirements before installation. Code “02” indicates right-hand rotation (clockwise viewed from shaft end). Incorrect rotation swaps suction and pressure ports, potentially damaging seals.
Coupling Alignment: Maintain shaft concentricity within 0.05 mm. Excessive misalignment causes premature bearing wear and shaft seal leakage, significantly reducing service life.
Inlet Line Negative Pressure: Inlet absolute pressure must not fall below 0.8 bar (vacuum not exceeding -0.2 bar). Use piping no smaller than the inlet port size and minimize elbows to prevent cavitation damage.
First-Start Priming: Fill the pump cavity with hydraulic oil from the outlet port before first start-up. Running dry or with trapped air will cause severe gear and bearing damage.
Fluid Cleanliness: Maintain system fluid cleanliness to ISO 4406 18/16/13 or better. Install a suction filter with minimum 100 μm rating and a return-line filter with 10 μm rating.
Product 2: Vivoil X2P Series High-Pressure Gear Pump (X2P5552ECBA / X2P5552ICBA / X2P555)

Key Technical Advantages
1. Group 2 Large Displacement Design
With 22.8 cc/rev displacement, theoretical flow reaches 68 L/min at 3000 rpm. The Group 2 platform delivers substantial flow capacity in a compact package—ideal for mobile hydraulic applications.
2. High-Strength Cast Iron End Cover
Cast iron end covers combined with high-strength aluminum body provide exceptional rigidity and pressure resistance while maintaining lightweight construction. Cast iron offers superior anti-deformation and impact resistance for high-pressure, shock-loaded mobile applications.
3. Pressure-Balanced Thrust Plate Technology
Integrated pressure-balanced thrust plates automatically compensate for gear end-face clearance, maintaining high volumetric efficiency under high-pressure conditions. This technology minimizes end-face leakage and extends stable operating life.
4. Wide Speed Range Capability
Supports 700 to 3500 rpm, accommodating everything from idle to full-speed operation. Stable flow output at low speeds with abundant flow at high speeds ensures versatility across diverse duty cycles.
5. SAE A Standard Flange and Splined Shaft
Industry-standard SAE A two-bolt flange and 5/8″ 9-tooth splined shaft ensure seamless interchangeability with Parker, Rexroth, and other major brands—no adapters required.
Application Areas
Mobile hydraulic equipment (loaders, forklifts, telehandlers)
Agricultural machinery (large tractors, combine harvesters)
Construction equipment (excavators, skid steer loaders)
Industrial hydraulic power units
Centralized lubrication systems
Expert Maintenance Tips
Rotation Direction Verification: Confirm rotation before installation. Code “52” indicates right-hand rotation (clockwise viewed from shaft end). Incorrect rotation swaps suction and pressure ports.
Spline Shaft Alignment: Maintain coupling-to-pump shaft concentricity within 0.10 mm. Angular misalignment in spline connections causes premature spline tooth wear and early failure.
Inlet Piping Sizing: Inlet piping diameter must not be smaller than the inlet port (3/4″ BSP). Undersized piping or excessive elbows increase inlet resistance, causing cavitation and noise.
Relief Valve Setting: System relief valve should be set no higher than the pump’s peak pressure of 250 bar. Full-relief return pressure should be set at 1.5× the rated discharge pressure.
Regular Oil Analysis: Perform oil sampling analysis every 500 operating hours to monitor fluid cleanliness and viscosity. Fluid contamination is the leading cause of gear pump failure—maintain cleanliness to ISO 4406 18/16/13 or better.
